More i look at this issue and try to compare it to ones i have seen for Windows 10 now, they are not the same exact issue. As yours flickers to black. We have done a clean boot to determine if any other drivers or software are causing this and result was, the issue persisted. Even disabling Shell extensions. Now say this happens only when clicking on something in windows, but mainly Start Menu.
Any chances can be monitor refresh rate problem or monitor issue. Other then that most will point towards then graphics card or it's drivers. Try reseating the card in PCI-E Slot. Only thing about this except refresh rate is, it would happen even if you did not do anything on screen. I have same GTX 970 but different brand, EVGA, no issues with new drivers or ones from the past.
As for Windows 10, I'll keep it. Its really nice OS, imo.
If going to think with staying with OS and tech support can not help, i would then try the clean install from a disc, may cause you to reinstall drivers and software, hopefully will solve an issue unless hardware is at fault.
I know PNY was a hit or miss brand, just like Zotac. Ironically, I never had problems with the GTX 560 gpu from Zotac on my i7 960 build. Currently, that gpu might be on its last legs. What makes you think you don't like PNY?
When I first have the GTX 970 SC (evga) card, the card causes driver crashes because of the unstable stock clocks from the factory, plus I get artifacts in Team Fortress 2. I sent the card for an RMA, and the RMA card I got was literary the same. Drivers crashing and causing artifacts in TF2. Then...I currently used the GTX 970 PNY and guess what....same artifacts and sometimes it cause a driver crash. It kinda makes me sad that I dunno what to do. Kinda ruined the gaming experience for me. Man, I miss that fun on the i7 960 system. Fun times.
I'll try clean install if the updated gpu drivers didn't help or tech support. Did Windows released the ISO of Windows 10? Do I have to go from 8.1 to 10 again? Since I have Samsung 850 EVO, I'll probably do a secure erase then put the clean install on that drive. Sadly, I've never done a secure erase on the SSD before so that got me a bit worry.
I think that was issue possibly with Team Fortress, wouldn't you think, happening on both cards and i have seen issues with this game and Windows 10 here., 1 game, not all games, right.
You have better i7 4790k, what's to miss, old games ? Think i posted links to Windows 10 ISO here, if not i will.No i do not think redoing upgrade is necessary. Inplace upgrade as mentioned here which i believe i linked if look back and will not loose anything, a refresh which you will loose all third party software, but not settings or reset or clean install from a disc, which of course will loose everything except a fresh OS install.
First possible choice, refresh Refresh Windows 10
Second choice InPlace repair upgrade Repair Install Windows 10 with an In-place Upgrade
Other choice on a reset like a clean install without a disc, no going back though Reset Windows 10

Remember with clean install need to reinstall all system drivers again. Some will get updated from Windows, suggest use link to manufacturer's site, most important, Intel Inf, Intel MEI, Lan drivers and you can get the Video card drivers from NVIDIA's site.
So you have artifact issues with TF2, too? I wouldn't think I be the only one who has that problem. I love the 4790k processor, no doubt. Its a sweet processor, but what I mean is that it kinda ruins the experience when I get artifacts on TF2. I didn't think I have problems with WoW, FC4, or something.
Thanks for the link, jds63. I'll do that around later.
See my specs i have EVGA similar to your model card. Never had to call support.
